PRESSED-STEEL CAR-=TRUCK.

SPECIFICATION forming part of Letters Patent N 0. 670.218, dated March19, 1901.

Application filed September 5, 1900 Serial No. 291090. (No model.)

To a, whom/ it may concern:

Be it kn own that I, ALEXANDER ZENOWSKE, a citizen of the United Statesof America, residing at Allegheny, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inPressed-Steel Car-Trucks, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in steelconstructions, and more particularly to pressed-steel trucks for cars.

The object of the invention is to provide means whereby a car-truckframe may be constructed of pressed-steel plates of a less thicknessthan is ordinarily employed, thereby lessening the cost of trucks ofthis type; and I accomplish this object by the peculiar manner ofbracing the side frame members or beams of the truck-frame at theirends, together with other details in construction as will be hereinafterdescribed.

With the above and other objects in view the invention consists in thenovel combinaiion and arrangement of parts to be hereinafier more fullydescribed, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate corresponding parts throughout theseveral views, in which Figure 1 is a vertical longitudinal sectionalView of my improved car-truck frame. Fig. 2 is a front elevation of thesame. Fig. 3 is a perspective view of a portion of the end of thetruck-frame. Fig. 4 is a like view of one of the sides of thetruck-frame. Fig. 5 is a detail perspective view of thestrengtheningplate. Fig. 6 is a perspective view of one of the hangers.Fig. 7 is a perspective view of the L-shaped angle-brace.

To construct a truck-frame in accordance with my invention, I providetwo side frame members or beams 1, each of which is cut away along theunder side of its ends, as at 3, serving to lighten the frame members orbeams and forming extensions 2. These side lar flange 7, provided atintervals with apertures 8. This liange 7, near each end of the sideframe members, is inclined as at 6. Y The side frame members are eachprovided with two vertical rows of apertures 9 10 to receive rivetswhich secure the strengthening-plates 16 to the side frame members orbeams These strengthening-plates are provided with apertures 16,registering with the apertures 9 10, two of the plates being providedfor each side frame member, one at each end. The plates are shaped toconform to the shape of the side frame members or beams at the ends ofthe latter and are each provided along the upper edge with aninwardly-extending flange 17, having apertures 18 registering with theapertures 8, near the ends of the flange 7, so that these two flangesmay be riveted together, as shown. The two side frame members or beams 1are connected together by transoms 11, of channel-beam form, whichtransoms have the strengthening-plates 16 formed integral withtheirends. The flange 12 along thetop edge .of the transoms is providedwith apertures 13,

and the flange 14 at the bottom or lower edge having apertures 15. Thesetransoms are riveted at the ends of their flanges to the flanges 4 and 7of the side frame members or beams. For supporting the car springs andbolster (not shown) I provide a pair of hangers 30 of substantially Ushape, the two vertical bars of which lie against the web of thechannelbar forming the transom and which are bent outwardly at rightangles at their upper ends, as shown at 21, this portion being providedwith an aperture 22, which registers with the apertures 13 in the flange12 of the transom to receive a-rivet for securing the hanger inposition. The ends 23 are bent downwardly into hook members to support apart of the brake apparatus. (Not shown.) The side frame members orbeams are further strengthened at their ends by angle-bars 25,substantially L-shaped and having apertures 26 2'7, and by channel-bars28,the flanges 29of which are provided with apertures 30. Thesechannel-bars are secured in the ends of the side frame members by thesame rivets which secure the flanges '7 17 together.

As the strain of the load is upon the truck at the ends of theside-frame members or beams it will be observed that I have by thisconstruction provided a truck-frame which is strengthened at the pointWhere this strain is greatest, the same being three ply at the ex tremeends and two ply from the transoms to the ends.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a car-truck frame, the side fram members or beams having ends ofless width than the body of the beam and provided withinwardly-extending flanges, angle-iron strengthening-bars ofsubstantially L shape secured to the beams at their ends, transoms ofchannel-bar form connecting the beams togerher, flangedstrengthening-plates secured to the inner face of the beams at each endthereof, and channel bars secured to the flanges of thestrengthening-plates, substantially as shown and described.

2. In a car-truck, the side frame members or beams having ends of lessWidth than the body of the beam, flanged strengthening plates secured tothe inner faces of said beams at their ends, channel-bars secured to theflanges of the strengthening-plates, and transoms of channel-bar formconnecting the side frame members or beams together, substantially asshown and described.

3. In a car-truck, side frame members or beams having ends of less widththan the body of the beam, flanged strengtheningplates secured to theinner face of the beams at their ends, channel-bars secured to theflanges of said strengthening-plates, transoms connecting the beamstogether, and hangers carried by said transoms, as and for the purposedescribed.

4:. A pressed-steel frame for car-trucks comprising side frame membersor beams flanged along the upper and lower edge and having ends of lesswidth than the body of the beam, flanged strengthening-plates secured tothe inner face of the beams at the ends thereof, channel-bars secured tothe flanges of the strengthening-plates, strengthening-bars ofangle-iron form secured to the strengtheningplates and channel-bars, andtransoms of channel-bar form connecting the side frame members or beamstogether, substantially as shown and described.

In testimony whereof I afiix my signature in the presence of twowitnesses.

ALEXANDER ZENOWSKE.
